Product Information for SSAC LLC44B30A SSAC Timing Relays, LLC4 Series Item# LLC44B30A - Liquid Level Control, 120VAC, 30Sec, Fill Operation, Adj Resistance LLC4 Series Information Single Probe Level Control for Conductive Liquids Adjustable or Fixed Sensing up to 250kOhms Selectable or Fixed Fill or Drain Operation Available 24, 120, or 230VAC Models are Available Isolated Pulsed DC on the Probes The LLC4 combines resistance sensing circuitry with solid-state timing to provide single probe level maintenance. On adjustable units, the sensitivity adjustment allows accurate level sensing while ignoring foaming agents and floating debris. Isolated pulsed DC is provided at the probe to prevent electrolysis. A trickle current of less than 1mA determines the presence or absence of conductive liquid between the probe and common. The LLC4 Series can be used with many types of low voltage (resistance changing) transducers to perform other control functions like temperature limit control, photo limit control, condensation sensing, and ice sensing. Drain (Pump-Down Mode): When the liquid level rises and touches the probe, the time delay begins. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay and LED energize and remain energized until the liquid level falls below the probe level. The output relay and LED de-energize and remain de-energized until the liquid rises and touches the probe. Fill (Pump-Up Mode): When the liquid level falls below the probe, the time delay begins. This time delay prevents rapid cycling of the output relay and its load. At the end of the time delay, the output relay and LED energize and remain energized until the liquid level rises and touches the probe. The output relay and LED then de-energize and remain de-energized until the liquid level again falls below the probe level. Isolated, 4A, SPDT Output Contacts
